Close design requirement；
7.3 model sheetinstallat
Reinforcement installation binding finishes, it is qualified by inspection after, start installation and reinforce riser and help template die plate, reinforce riser and help
Plate graded casting concrete, needs to pay special attention to the verticality of template, flatness and faulting of slab ends control in construction；
7.4 concreting
Before concreting, template position deviation, cross dimensions, surface smoothness, absolute altitude and bracing reinforcement should be checked
Situation etc., can carry out pouring for concrete after passed examination；
For height of the discharge port away from concreting face no more than 1m, layer-by-layer distribution, has poured one layer during casting concrete
Pour the second layer again afterwards, paving thickness is not preferably greater than 30cm；
Concreting should be carried out continuously, and must not be interrupted, and when pause interval for some reason, its intermittent time should be less than front layer and mix
Coagulate the presetting period of soil；, should be by pouring interrupt processing when more than the intermittent time is allowed, while answer indwelling construction joint, construction joint
Plane should be with the axis perpendicular of structure；
It after concreting, should in time repair, smooth out concrete exposed surface；
7.5 stent, form removable
With the related request of 5.5 form removables；
7.6 spilled water holes are installed
When installation reinforces riser, helps template die plate, while spilled water hole is installed, spilled water hole is installed in strict accordance with design drawing lateral
Model requires to carry out, and sluicing pitch of holes can be set by 2m~3m, in installation process it is noted that setting and the spilled water hole slope of rubble anti-filter
The angle of degree；
7.7 wall body subsiding cracks are constructed

Land pebble, gravelly soil, circle gravel soil, dust soil and fine sand, glutinous sand, emery dust soil, sand clay) or its above rank filler, sluicing
Hole water inlet is wrapped up using permeable geotextiles, installs 5cm thickness plastic draining sheet materials in time, then carries out wall by reinforcing riser height
Placement in layers is constructed afterwards, individual layer filled slope≤300mm, and mechanically or manually compaction in layers, backfill compacting system are utilized after filling
Number >=0.94, it is noted that finished product protection during filling.
Although the embodiment of the utility model has been shown and described above, it is to be understood that above-described embodiment is
Exemplary, it is impossible to the limitation to the utility model is interpreted as, those of ordinary skill in the art are in the scope of the utility model
It is interior above-described embodiment to be changed, changed, replaced and modification.
